A CBPR INVESTIGATION OF TRAFFIC POLLUTION AND CVD IN PUERTO RICAN ADULTS

我们已经分析了来自波多黎各老年人预期队列的横断面数据，以了解 靠近主要道路和住所附近的交通密度。这项分析没有评估水平 因为队列研究最初并不是为了评估这种接触而设计的。尽管如此，使用流量 作为一个代理，我们已经证明了交通距离与高血压、血压、 C反应蛋白和血清白蛋白。据OIU所知，这是第一次在波多黎各人口中评估交通暴露和心血管疾病(CVD)标志物的研究，波多黎各人口是危险因素和心血管疾病发病率较高的人群。有相互竞争的证据表明，细颗粒物(PM2.5)与心血管疾病有关。然而，PM的这一部分相当均匀地分布在不同城市的不同地理区域，但在交通繁忙的情况下几乎没有增加。然而，超细颗粒物污染(UFP)是极小的颗粒物，已被证明在高速公路和人流频繁的道路附近局部升高。除了我们的研究外，研究还表明，交通便利与心血管疾病之间存在关联。 因此，我们将解决交通污染在波多黎各人口健康差距中的作用，并制定证据证明UFP和心血管疾病之间是否存在因果联系。我们提出了三项以社区为基础的参与性研究，积极让我们的社区合作伙伴参与研究过程。研究一将在我们前期工作的基础上，开发我们研究区域内UFP暴露的模型，以测试环境UFP暴露与核心队列中心血管疾病的相关性(中心的项目1)。研究二将在核心队列中的20名参与者的家中安装HEPA空气过滤器，并评估家庭中减少UFP是否与炎症标志物的改善有关，包括C-反应蛋白、IL6、纤维蛋白原和肿瘤坏死因子-a。第三项研究将开发和传播 向当地波多黎各人提供与交通相关的污染和心血管疾病的教育材料。

We have analyzed cross sectional data from the Prospective Cohort of Older Puerto Ricans for the effects of proximity to major roadways and density of traffic near their residences. This analysis did not assess levels of pollution because the cohort study was not originally designed to assess this exposure. Still, using traffic as a proxy, we have demonstrated associations between traffic proximity and hypertension, blood pressure, C-reactive protein and serum albumin. To oiu- knowledge this is the first study to assess traffic exposure and cardiovascular disease (CVD) markers in a Puerto Rican population, a population that has high prevalence of risk factors and cardiovascular diseases. There is competing evidence that fine particulate matter (PM2.5) is associated with CVD. However, this fraction of PM is spread fairly evenly across geographic areas with variation within cities, but little increase next to heavy traffic. Ultrafine particulate pollution (UFP), which are extremely small particles have, however, been shown to be elevated locally near highways and heavily traveled roadways. Research besides ours also has shown associations between proximity to traffic and CVD. Thus, we will address both the role of traffic pollution in health disparities in the Puerto Rican population and develop evidence about whether there is a causal link between UFP and CVD. We propose three community-based participatory research studies that actively engage our community partners in the research process. Study one will build on our preliminary work and develop a model of UFP exposure across our study area in order to test associations of ambient UFP exposure with CVD in the core cohort (project 1 for the center). Study two will install HEPA air filtration in homes of 20 participants in the core cohort and assess whether reducing UFP in the home is associated with improvements in markers of inflammation, including C-reactive protein, IL6, fibrinogen and TNF-a. Study three will develop and disseminate educational materials about traffic-related pollution and CVD to the local Puerto Rican population.
